Noise reduction works, than it doesn't.
There is strange behaviour with QSVEnc when using --vpp-convolution3d and batch encoding.
In the first video that gets encoded, the noise/grain gets removed. The noise/grain gets enhanced/multiplied strangely in each following video.
I need help figuring out where the issue is coming from. When I encode them individually, the problem does not occur. I use a Windows batch script for QSVEnc operations.
When I encode them individually, the problem does not occur.
Then there should be something wrong with the bat script.
I don't have such strange behavior, in general each process will not be affected by the other (previous) process.
The batch is a simple for-loop. That shouldn't be the problem, as I have been using for-loops since long ago.
However, I noticed the issue could be related to my multi-GPU setup and usage of the --device option.
When I remove the option --device 1 or --device 2 from my command and let QSVEnc select the device, the --vpp-convolution3d option results looks ok, I tested 20 grainy files and trimm 5000 frames windows for the testing, as I always do when testing filters.
I'm very surprised that it only happens with --vpp-convolution3d or maybe I didn't notice it with the other noise removal filters as I don't use them so often.

I did some more testing, and it pinpointed that option when multiple GPUs are used.
I tested running the batch and let only one GPU do the job.
As soon as --device is removed, the issue disappears.
Are there any logs I can provide that might reveal anything?
Ok. I was able to determine the culprit of the issues. I am using a multi-GPU setup for my testing, including the iGPU. 1st, I switched off the iGPU to see if that solved the problem, but the issue persisted. Then I remembered that I activated the Graphic Preference in Windows > System > Display > Graphics > Selected App (QSVenc). I removed that option since I also deactivated the iGPU. Now, the processing seems to perform as intended. I will conduct some further tests and report back. Thank you.
Confirmed behaviour related to the specific settings and hardware scenario. Therefore closing the issue.
